Read and Write Mission Via Mavlink

I want to read the existing mission plan in pixhawk with mavlink commands and upload a new mission plan, is this possible? Thanks in advance.

It is possible and the instructions on how to do that are on the mavlink website. Or you can use pymavlink.

Here is a detailed example:

github.com

ArduPilot/MAVProxy/blob/master/MAVProxy/modules/mavproxy_wp.py

#!/usr/bin/env python
'''waypoint command handling'''

import time, os, fnmatch, copy, platform, struct
from pymavlink import mavutil, mavwp
from MAVProxy.modules.lib import mp_module
from MAVProxy.modules.lib import mp_util
if mp_util.has_wxpython:
    from MAVProxy.modules.lib.mp_menu import *

try:
    # py2
    from StringIO import StringIO as SIO
except ImportError:
    # py3
    from io import BytesIO as SIO
    
class WPModule(mp_module.MPModule):
    def __init__(self, mpstate):
        super(WPModule, self).__init__(mpstate, "wp", "waypoint handling", public = True)

Thanks, can I do this with C? I don’t know python.

Yes, you only have to use MAVLink libraries in C language.
